This is only "shadow work" relative to the status quo, and there's no principled reason to privilege the status quo over the alternative. You could just as easily say that tying your shoes is "shadow work" because you at one point could have paid a butler to do it for you (and still can, I suppose). This is true of any of a million things that you do for yourself that you could pay a taskrabbit to do instead. So the claim that "shadow work" is becoming more prevalent doesn't make a ton of sense, especially when you net it out with the types of labor that are becoming newly salable (through taskrabbit and all the other forms of the gig economy).
